For a different view, here is the latest length, coiled.  It’s about 6″ longer than the last picture.

Another possibility with this design might be to combine colors within each spiral, and make more of a blended design without as much contrast. For example, one spiral blue and purple 15s, the next purple and green, and the last green and blue. That might be an interesting spiral, and perhaps with 2mm Swarovski rounds as the accent bead on the outside of the spiral. Maybe all the same color Swarovski, perhaps black? With a black core?
